Zoom H2 Hack 

Written By: Berto 


For a music band, synchronous 4-track sound recording is the absolute minimal setup. 
Recording instruments on four discrete channels improves the sound quality and makes the 
master mix easy. The Zoom H2 has that (hidden) opportunity, because it can record sound 
from the 4 built-in microphones simultaneously. The only thing we need to do is to add 4 line 
input plugs and 2 switches. To change the sound level we solder some resistors and 
capacitors into the box. As reward for the modification you get a cheap multi-track field 
recorder in the palm of your hands. 

The video below shows how to get it done.

Step 1 — Zoom H2 Hack

• The Zoom H2 can record 4 tracks simultaneously but only using its 4 built-in microphones. 
This modification makes recording of 4 signals at line level possible. 

• You have to install 4 input jacks on the back of the unit. The resistors shown in the 
diagram reduce the input signal by 40dB. The capacitor blocks the DC part from the input. 
Switch S1 chooses line input or microphone. 

• After drilling the holes on the back of the H2, install the 4 jacks and the 2 switches. RCA 
jacks are used here but other kinds of inputs are also possible. 

Step 2 

• Now for the soldering part. Take care with the soldering iron; there is not much room inside 
the box. Watch for short circuits. Insulate when necessary. Work clean; check the 

• The middle photo shows how the switch is connected to the 4 microphones at the top. 

• The right photo shows the compact placement of the new components.

Step 3 

• The left photo shows the soldering of the resistors on the input jacks. They have to be 
pressed into place beside the jack. 

• The middle photo shows the Zoom H2 connected to the 4 outputs of the sound interface (8 
channels in total). 

• The last photo shows the H2 in recording mode. You can see the display with the volume 
meters. Here you can check the volume levels. You can change the gain using the gain 
slider. This is the finished product. Success!!! 

You need some experience with soldering small connections. You need to have the courage to 
open the recorder and to make this hack in a crowded enclosure.
